States in the Southeast that had banned gay marriage prior to last week’s Supreme Court decision legalizing it stand to gain the most from the ruling financially, according to a report compiled at the end of last year by the Williams Institute at UCLA and Credit Suisse.
The study found that states in the Southeast could see a total economic benefit of $733 million in the first three years after legalization of gay marriage, thanks to pent up demand and increased spending on weddings and tourism.
Researchers estimated that gay marriage spending nationwide could reach $2.6 billion over the next three years. Gay couples tend to have smaller weddings, with an average of less than 80 guests, according to TheKnot.

Men spend an average of $15,992 on their wedding, while women spend an average of $13,055. More than 20 percent of gay couples spend more than $20,000 on their nuptials. The average opposite-sex marriage costs more than $31,000.
In addition to boosting consumer spending, which helps GDP, the ruling may also be a boon to federal coffers. While married couples now benefit from the financial protections of marriage, they also now have to pay the tax penalty.
The legalization of gay marriage in New York in 2011 led to an estimated $259 million in spending and $16 million in revenues for New York City, according to the mayor’s office.
